Celebrities at Princess Eugenie's Wedding: Meghan Markle, Prince Harry and Who Else?

Prince Harry and Meghan Markle, the Duke and Duchess of Sussex, were in attendance at Princess Eugenie's wedding with Jack Brooksbank on Friday. They sat beside Harry's brother, Prince William and his wife, Kate Middleton, Duchess of Cambridge.

There was speculation the couple would not make it to the wedding at St. George's Chapel at Windsor Castle—the same location where they tied the knot five months ago—because they are slated to embark on a 15-day royal tour to Australia on October 16.

Markle was dressed head-to-toe in navy blue, wearing a coat and dress designed by Givenchy, who also created her May wedding dress. The duchess sported a matching blue hat by Noel Stewart. A hat-less Harry wore a grey, pinstriped suit and a black topcoat with tails.

Along with members of the royal family—including Eugenie's grandparents Queen Elizabeth II and Prince Phillip—several famous faces were among guests at the second royal wedding of the year. British singer and model Pixie Geldof was one of the first to arrive at the ceremony, along with the likes of Cara Delevingne, Demi Moore, Liv Tyler, Dave Gardner, Naomi Campbell, Robbie Williams, Ayda Field, Ellie Goulding and many others.

Surprisingly, George and Amal Clooney were not at the royal wedding. It was speculated the couple was invited due to Brooksbank's relationship with George Clooney. Brooksbank is the brand ambassador for Casamigos tequila, formerly owned by George Clooney.

Eugenie and Brooksbank wedding was considerably larger than Harry and Markle's martial festivities earlier this year. While 600 people attended the Duke and Duchess of Sussex's ceremony, 850 guests were invited to Eugenie's wedding.

Neither of this year's royal weddings was considered state affairs—unlike William's 2011 wedding attended by 1,900 people—but there was a significant reason why Eugenie's guest list topped her cousin's, according to Eugenie's father, Prince Andrew of York. He appeared in an interview on ITV's This Morning on Friday and said there were more people at the ceremony because "Eugenie and Jack have so many friends."
